I need to lower the drive pulley on the shaft of the stepper motor for the Z axis on my Chinese laser. Normally I would use a sleeve and a small hammer to tap the pulley to a lower position on the motor shaft on a standard electric motor. However, I'm not sure this would be an acceptable method on a stepper motor.
A "square key" is used to "lock" the drive pulley to the stepper motor shaft
The drive pulley appears to be "pressed on" to the stepper motor shaft
There is no set screw or other type of mechanical device to secure the drive pulley to the stepper motor shaft
Is it acceptable to use a sleeve and small hammer to tap the pulley to lower the pulley on a stepper motor shaft or should another method be utilized?
Thank you,
Roger
